which following-is a specification.

s venties" relates to improvements in uncouplin hanisrns, and has for'its object thprov de a new and improved form of devicewhich'inay be cheaply and readily manufaeturerh and, which may be easily at.-

tached amidetach'ed from acar.

Still another object of my invention" is to provide a mechanism of the class described comprising but two operating parts'and arranged to be mounted so that the operator may pull the operating lever toward him and the side of the car to uncouple the same, thereby obviating the danger of standing between the cars to uncouple the same.

Still another object is to provide a mecha nism of the class described which may be attached to the end sill of a car leaving the hand hold carried thereby unrestricted so as to comply with Interstate Commerce regulations and the like.

These and other objects will be set forth and shown in the following specification and accompanying drawing, in which;

Figure 1 is a perspective ofmy mechanism showing the same applied to the end sill of a car; Fig. 2 a plan view of the same; Fig. 3 is a detail section through one of the pivotal supports.

' Like numerals refer to like elements throughout the drawings, in which; 10 designates generally a car having an end sill 11, and coupler 12 provided with the usual coupler pin 13. The latter has the loop or eye 13 for engagement by the coupler mechanism which comprises in my invention, what I term the uncoupler rod 15 and operating lever 16. The former is provided with the eye or loop 15 loosely mounted on the pivotal support 17 On the coupler side of this pivotal support 17 the coupler rod is bent outwardly, as indicated by numeral 15, see Fig. 2. The rod 15 is further provided with the portion 15 angularly bent with respect to portion 15 and fitting loosely through the loop 13*"* of the coupler 13. The rod 15 is further provided with the portion 15 on the opposite side of the mounting 17 this portion terminating in the eye or loop out cramping or EQUIPMENT COMPANY, A conroRA'rIoN'o DELAwABn nn'conrnnte MEoHl nIs Y i; Specification of Letters Patent. v Patented June 1914, I 5 Application filed February 16.1914.

15 and normally diverging slightly from the end of the car, as shown in Fig 2. operating lever is formed with the angularly disposed arms 16 16', the lattercomeprising an engaging handle. In the em-. bodiment shown, the rod 16 is bent to form the said arms and is provided with the en .enoneno. MURRAY, or cinema, rumors..- Ass euon 'ro 'Knzoimmme;

The

largcd loop or eye 16 at the intersection of eye 15 of rod 15, the handle arm 16 being these arms, this loop passing through :the

located outwardly of arm 16 to insure sufiicient clearance between the same and the end sill. At its extremity, the arm 16 is.

looped or apertured, as'indicated by numeral 16 and is loosely mounted upon a piv-.

otal mounting 18, similar to 17 In its normal coupling position, as shown in Fig. 1, the arm 16 extends downwardly slightlv from the loop 1 v The operation of the device is as follows :lVhen it is desired to uncouple the cars or raise the coupler pin 13, arm 16 is pulled toward the adjacent side of the car 10, the loop 16 thereby being rotated in an are about pivotal mounting 18. At the same time the portion 15 of coupler 15 is pulled downwardly and portion 15 thereof is raised, operating to raise the coupler pin 13 to uncoupling or lock said position. This pivotal movement of the rod 15 is made possible by the elongated loop 16 and the loose engagement therewith of loop 15 and by inclining the arm 16*- upwardly from mounting 18, it will be apparent that loop 16 and loop 15 move both upwardly and downwardly of a horizontal line through the mounting 18, so that the lateral relative movement of operating lever 16 and uncoupling rod 15 is reduced to a minimum. The loose mounting of rod 15 upon the pivotal support 17, and the similar mounting of rod 16 upon mounting 18, together with the play between the looped portions 15 16, enables the required motion of the coupler 12 in all directions to take place withbending the coupler mechanism. Similarly by the outward divergence of the arms 15 and 16 from the end sill, inward movement of the same when caused by the outward movement of the coupler, will be permitted; also the arrangement and construction of my mecha nism permits the placing of the hand hold 19 in its most advantageous position without hampering the use thereof.

In Fig. 3 I have shown in detail the construction of the pivotal mounting 17, in which I utilize a sleeve or thimble 17 having the circular shoulder l7 therearound. This sleeve or thimble is provided with the socket 17 in its base, preierably non-circular to form a seat for the similarly shaped head 17 of bolt 17 which extends through the thimble 1'7 and projects outwardly thereof. A washer or collar 17 is fitted on the reduced portion of thimble 17 and rests against the shoulder 17*. Similarly a Washer or collar 17 rests against the outer end of the thimble 17 and is normally secured in place by the nut 1'2 threaded on the end of bolt 17, the same serving to hold'the collar 17 in place and also serving to securely clamp the head of the bolt 17 securely in its" socket 17. The looped portion 15 of the rod 15 fits loosely over the reduced portion of thimble 17' between the collars 17,'17 and itis apparent that the same. may be readily detached therefrom by removing the nut 17 and collar 17 Pivotal mounting 18 is similar in construction and arrangement and need not bedescribed in detail.

oaaeea It will be apparent that my invention is 5 susceptible of many modifications and improvements, and I do not wish to be restricted to the same beyond the scope of the appended claim. J

What I claim is An uncoupling mechanism comprising an uncoupling rod pivotally mounted intermediate its extremities and operatively engaging a coupler pin, said rod being provided with an aperture adjacent one extremity, an operatingrod-eomprising angularly disposed, arms, one of said arms being pivotally mountedfithe other of said arms pro- Viding an operating handle, said rod being provided with an aperture adjacent the intersection of said arms, said aperture loosely engaging the aperture of said uncoupling rod, one of said apertures being enlarged to permit free pivotal movement of said uncouplin and operating rods,

In testimony w ereof, I have subscribed my name.
